Question

A 27 kg child goes down a straight slide inclined 38? above horizontal. The child is acted on by his weight, the normal force from the slide, and kinetic friction.

Part A How large is the normal force of the slide on the child? Express your answer to two significant figures and include the appropriate units.

Part B Choose the correct free-body diagram of the child.
